Hong Kong-Zhuhai-Macau Bridge

The Hong Kong–Zhuhai–Macau Bridge (also known as HKZM) is a design-build project that will span some 31 miles across the Pearl River Delta. When completed, its series of bridges, man-made islands, roads and tunnels will be the longest cross-sea combined highway in the world, connecting Hong Kong with Macau.

The design-builder, China Communications Construction Company, broke ground in 2009 with a promise to finish the project by 2016 at an estimated cost of $10.6 billion. Delays have ensued, however, including a shifting artificial island, a scandal over faked concrete tests, and environmental litigation. Nine workers have died on the job and up to 600 more have been injured – and reported costs have climbed to $11.4 billion. The media has reported the project could open as late as 2021.
